Answer:
2 : 1
Explanation:
[tex]\sf area \ of \ sector: \dfrac{\theta}{360} \pi r^2[/tex]
1st sector:
[tex]\sf \rightarrow area: \dfrac{80}{360} \pi (8)^2 = 44.68 \ cm^2[/tex]
2nd sector:
[tex]\sf \rightarrow area: \dfrac{160}{360} \pi (4)^2 = 22.34 \ cm^2[/tex]
Ratio of 1st sector to 2nd sector:
44.68 : 22.34
2 : 1
